Abstract
A bicycle training and exercise device for stationary operation of a bicycle thereon, the device having roller and beltway members forming a riding platform for the bicycle, and a plurality of lever arms for supporting the bicycle on the device. The lever arms of the bicycle are movable laterally in response to lateral movements of the bicycle. The pivotally joined lever arms provide substantial support for the bicycle and rider while closely simulating actual riding conditions.
Claims
exact text as granted — not AI-modifiedI claim:
1. A bicycle training and exercise device comprising roller and beltway means for stationary operation of a bicycle thereon, right and left stanchion means disposed one to each side of the bicycle, a plurality of substantially rigid lever arms in side-by-side relationship, said arms being journaled together with bearing means for relative pivotal movement and secured to the bicycle and to said stanchion means, said lever arms also being laterally movable with respect to one another in response to lateral movements of the bicycle.
2. A bicycle training device as defined in claim 1 in which said stanchion means are disposed generally vertically and are vertically adjustable.
3. A bicycle training device as defined in claim 1 in which said lever arms are disposed to form side-by-side V-shaped members, with the central portion being releasably secured to the bicycle frame and the outermost end portions are respectively secured to said stanchion means.
4. A bicycle training device as defined in claim 3 and including restraining means secured to and extending between the open ends of said V-shaped members.
5. A bicycle training device as defined in claim 4 in which said device includes a generally horizontal, telescoping bar means secured at one end to said central portion and at the opposite end to the bicycle frame.
6. A bicycle training device as defined in claim 1 in which said bearing means are disposed at the points of connection of said lever arms to said stanchion means and at the points of connection between adjacent lever arms.
7. A bicycle training device as defined in claim 6 in which said stanchion means are disposed generally vertically and are vertically adjustable.
8. A bicycle training device as defined in claim 7 in which said lever arm means are disposed to form side-by-side V-shaped members, with the central portion being releasably secured to the bicycle frame and the outermost end portions are respectively secured to said stanchion means.
9. A bicycle training and exercise device for stationary operation of a bicycle having roller and beltway means upon which the bicycle is supported, wherein the improvement comprises stanchion means on each side of the bicycle, a plurality of lever arm means journalled together for relative pivotal movement and disposed to form side-by-side V-shaped members, said journalled arms having an inner central portion releasably secured to the bicycle frame and outer end portions respectively secured to said stanchion means for supporting the bicycle on the roller and beltway means, said lever arm means also being laterally movable with respect to one another in response to lateral movements of the bicycle.
10. A bicycle training device as defined in claim 9 in which said stanchion means are disposed generally vertically and are vertically adjustable.
11. A bicycle training device as defined in claim 9 and including restraining means secured to and extending between the open ends of said V-shaped members.
12. A bicycle training device as defined in claim 11 in which said device includes a generally horizontal, telescoping bar means secured at one end to said central portion and at the opposite end to the bicycle frame.
13. A bicycle training device as defined in claim 9 in which said lever arm means have self-aligning bearing means disposed at the points of connection of said lever arms to said stanchion means and at the points of connection between adjacent lever arms.
14. A bicycle training device as defined in claim 13 in which said stanchion means are disposed generally vertically and are vertically adjustable.
15. A bicycle training device as defined in claim 14 in which said lever arm means are disposed to form side-by-side V-shaped members, with the central portion being releasably secured to the bicycle frame and the outermost end portions are respectively secured to said stanchion means.
16. A bicycle training device as defined in claim 9 in which said device includes an elongated, telescoping bar means secured at one end to said lever arm means and at the opposite end to the bicycle frame.
17. A bicycle training device as defined in claim 16 in which said device includes side restraining means disposed generally parallel to and slightly above the beltway for preventing the bicycle wheels from leaving the beltway.Join the waitlist — get patent alerts
